“…Related to soil acidity attributes vermicompost also had respectable response as reported by Wael et al (2011) stated that vermicompost was used to increase the pH in acidic soils and reduce Al and Mn toxicity because of its alkalinity. Study in the western Ethiopia acidic soil showed that Vermicompost application at different application rate had gave significant effects (Abdissa et al, 2018), on soil acidity features like soil pH, exchangeable acidity and soil acid saturation percentage which was positively affected like other soil physicochemical properties due to application of vermicompost which was prepared from most preferred raw materials.…”

Several research activities were conducted to improve the productivity of degraded and less fertile soils of Ethiopian, among the most crop yield-limiting essential nutrients phosphorus is the major ones next to nitrogen moreover which is sourced from non-renewable natural resource and its limited reserve will vanish within few decades if the world fertilizer consumption will continue as it is. Phosphorus deficiency and losses problem is more sensitive in acidic soils which are widely spread in southern, western, southwestern, northwestern, and most of central Ethiopia its level becomes even more worst. Consequently, seeking multiple ways of improving the nutrient use efficiency and minimizing losses to the environment should be considered. Several forms of phosphorus fertilizers were commonly used which includes organic and inorganic forms it has its own merits and demerits on the efficient uses of phosphorus for crop production. Optimizing soil pH is crucial for acidic soil by using lime (CaCO3) and other different liming materials like farmyard manure, vermicompost, and biochar as an alternative it's also possible to improve soil pH by direct application of rock phosphate and partially acidulated fertilizer products on acidic soils which minimize the cost which was incurred for acidulation process on industrial fertilizer production. On the other hand, using blended lime with the most limiting essential nutrients based on soil fertility status will improve both efficiency and application costs with other multiple advantages over the classic ones.

“…The effective cation exchange capacity of the soil was significantly affected by all treatments except the chemical P fertilizers when applied at the rate of 40 and 60 kg ha -1 . The increase was due to improved soil condition by vermicompost and lime and increase of negative charges on the surface of the soil colloids (Bekela et al, 2018) [3] . Mahmoud and Ibrahim (2012) [21] reported that CEC was increased significantly with the application of vermicompost alone and it's in combination with water treated residue.…”

A long term imbalanced use of fertilizers is adversely affecting the sustainability of agricultural production eventually causing environmental pollution. The major issue for the sustainable agricultural production will be management of soil organic carbon and rational use of organic inputs as integrated plant resource management. It play a vital role in improving stocks of plant nutrient in soil by increasing the efficiency of plant nutrients, thus limiting losses to the environment. It optimize the function of the soil biosphere and ultimately sustaining the physical, chemical and biological function of soil. This paper has reviewed the research work carried out by various scientist on impact of integrated nutrient management on different soil chemical properties in India and abroad.

Understanding the nutrient dynamics in acid soil is fundamental to carry out proper management. The study was conducted to investigate phosphorus (P) pools and selected properties under different rates of lime for acid nitisols of Farawocha, Southern Ethiopia. Four lime rates incubated for a month in three replications were tested. The lime rates were 0 t/ha (0%), 5.25 t/ha (50%), 10.5 t/ha (100%), and 15.75 t/ha (150%). Lime requirement (LR) for 100% was calculated targeting soil pH of 6.5. Data on the P pools such as soluble P (P-sol) and bounded forms of P with iron (Fe-P), aluminum (Al-P), calcium (Ca-P), organic part (Org-P), residual P (Res-P), and total of P fractions were measured. In addition, changes in soil chemical properties such as pH, exchangeable acidity, calcium (Ca), magnesium (Mg), sulfur (S), iron (Fe), copper (Cu), boron (B), zinc (Zn), and manganese (Mn) were analyzed. The result showed that total P was 357.5 mg/kg. Compared to nontreated soil, liming at a rate of 15.75 t/ha significantly improved P-sol (34.2%, r2 = 0.88), Ca-P (61.6%, r2 = 0.92), and Res-P (195%, r2 = 0.94); however, it reduced Fe-P (58.5%, r2 = −0.83), Al-P (71%, r2 = −0.97), and Org-P (19.1%, r2 = 0.93). Overall, the P-associated fractions in the soil, regardless of the lime rates, were in the order of Org_P > Res_P > Fe_P > Ca_P > Al_P > P-sol. Liming raised soil pH by 2.1 units (4.5 to 6.6) over nonlimed soil, whereas it reduced exchangeable acidity from 4.18 to 0.23 meq/100 g soil. Available P, Ca, Mg, S, Cu, Zn, and B contents were significantly improved with lime application. However, liming reduced Fe and Mn contents. In conclusion, these findings showed that liming facilitated the release of P from various pools, modified pH and exchangeable acidity, and resulted in beneficial changes for most of the soil chemical properties.
